Digital broadcasting system and method of processing data in digital broadcasting system
First Claim
1. A method for processing a broadcast signal, the method comprising:
- receiving the broadcast signal;
demodulating the received broadcast signal;
decoding first signaling data from a signal frame in the demodulated broadcast signal, the first signaling data including information for fast service acquisition;
decoding multiplexed data in the demodulated broadcast signal,wherein the multiplexed data includes second signaling data and channels belonging to the multiplexed data,wherein the channels carry components of services,wherein the channels and the second signaling data are encapsulated into user datagram protocol/internet protocol (UDP/IP) packets, andwherein the second signaling data provides access information for the channels;
decoding the second signaling data; and
decoding the components of the service.

Abstract
A digital broadcasting system and a data processing method are disclosed. The data processing method includes receiving a broadcast signal in which main service data and mobile service data are multiplexed, demodulating the broadcast signal to acquire fast-information-channel signaling information including reference time information for a system clock, and outputting demodulation time information of a specific position of a frame of the broadcast signal, decoding the fast-information-channel signaling information, and establishing the reference time information as the system clock at a demodulation time according to on the outputted demodulation time information and decoding the mobile service data according to the system clock.
